Xerosis cutis is the medical term for abnormally dry skin, which derives from the Greek word xero, meaning dry.
Dry skin is a common skin condition characterized by a lack of moisture in the epidermis.
The main cause of dry skin is dry air, or low humidity, in both inside and outside environments. Keep homes moist by using a humidifier.
The daily shower routine, prolonged exposure to hot water and harsh soaps, greatly perpetuates dry skin. Showers should be kept short, water should be warm rather than hot, and skin should be patted dry with a towel afterwards instead of rubbing.
As skin ages over the years, hormone levels change and the skin becomes thin and dehydrated.
